WebbHOOF (Histogram of Optical Flow) One of them is Handcrafted features that we use different methods like SIFT, SURF, etc. to obtain useful features. And the other is deep learning based approaches that we use … WebbIn this paper, we exploit the advantage of correlation and optical flow based trackers to achieve drift free tracking. Hence, we apply the CF-based tracker to track an object and switch to the modified median flow tracker during the drift conditions. The combined model is optimized to cope up with the fast appearance change and recover from ...
